Protocols for Relay-Assisted Free-Space Optical Systems
Nestor D. Chatzidiamantis, Diomidis S. Michalopoulos, Emmanouil E. Kriezis +2
We investigate transmission protocols for relay-assisted free-space optical (FSO) systems, when multiple parallel relays are employed and there is no direct link between the source…
Buffers Improve the Performance of Relay Selection
Aissa Ikhlef, Diomidis S. Michalopoulos, Robert Schober
We show that the performance of relay selection can be improved by employing relays with buffers. Under the idealized assumption that no buffer is full or empty, the best source-re…
Selective Cooperative Relaying over Time-Varying Channels
Diomidis S. Michalopoulos, Athanasios S. Lioumpas, George K. Karagiannidis +1
In selective cooperative relaying only a single relay out of the set of available relays is activated, hence the available power and bandwidth resources are efficiently utilized. H…
